Spark plugs replace at planned maintenance service.
If it is necessary to replace ever spark plugs not at planned maintenance service, it is necessary to take into consideration the following.
Spark plugs and all system of ignition as a whole are picked up to the given engine, and it promotes decrease in quantity of harmful substances in the fulfilled gases.
To avoid failures of the engine, decrease in its capacity, deterioration приемистости, increases of the maintenance of harmful substances in the fulfilled gases and creations of hindrances for radio reception, it is necessary to apply only recommended by concern a Volkswagen of a spark plug to the given engine. Especially important characteristics of candles are quantity of electrodes, калильное number and on occasion ability not to create hindrances to radio reception.
Correct functioning of spark plugs – one of the major conditions of effective work of the engine. It is necessary, that on the engine spark plugs only the ordered type have been established. At the serviceable engine cleaning of spark plugs – rare operation.
The engine 1,6-I
Arrangement of screws (1) fastenings of the top casing of the engine 1,6-I
Arrangement of tips (2) high-voltage wires on spark plugs
The engine 1,8-I
Arrangement скоб (1) fastenings of the top casing of the engine 1,8-I
Arrangement of tips of high-voltage wires on engine spark plugs 1,8-I
Engines 2,3-I (5 cylinders)
Arrangement of tips of high-voltage wires on engine spark plugs 2,3-I
Engines 2,8-I (6 cylinders)
Arrangement of screws of fastening of the top casing of the engine 2,8-I
The visual control of a working part of spark plugs can show an engine condition. If a nasal part of an insulator of spark plugs pure and white, without a touch it testifies to too poor mix. It also specifies that the candle too hot, that is warmly from the central electrode is taken away slowly. If it so it is necessary to adjust structure of a fuel mix or to replace a candle.
If the nasal part of an insulator is covered by black touch, it means that a mix too rich. If a touch black and oily it is the witness ствует about deterioration of the engine and necessity of its check and repair. If the nasal part of an insulator is covered by light brown touch the mix structure is optimum also the engine is in a good condition.
The interelectrode backlash of a spark plug is of great importance, as at too big and at too small backlash the size of a spark that leads to decrease in an overall performance of the engine changes. The backlash should correspond to technical requirements always.
Measurement of a backlash of a spark plug щупом
Backlash check is carried out by a wire template or щупом. Backlash updating is carried out подгибанием a lateral electrode. The central electrode in no event cannot be bent, as it can lead to breakage of an insulator and a candle exit out of operation.
For подгибания a lateral electrode of a candle it is necessary to use the special tool.
Before spark plug installation in the engine, check up, that the carving was pure and all threads of a carving whole.
Screw in spark plugs by hand and then tighten their demanded moment.
Connect to spark plugs high-voltage wires.
